A case of lacrimal gland dirofilariasis.

A patient with a diagnosis of chronic and idiopathic unilateral dacryoadenitis was submitted to our clinic for diagnostic reasons from a regional hospital. Within a period of 1 year, this was the second onset of a swelling in the region of the lacrimal gland which - unlike the first time - showed resistance to antibiotic treatment. The patient's general and ophthalmic condition was good, and his only complaint was of cosmetic nature because of the disfiguring swelling in the lateral part of the left upper eyelid. Basic laboratory findings showed no abnormalities and radiographic imaging showed enlargement of the left lacrimal gland without bony destruction. Guided by epidemiological data for noninfectious dacryoadenitis we decided to perform excisional biopsy of the left lacrimal gland. To our surprise, the pathologist verified the presence of a worm of the genus Dirofilaria, which is, to the best of our knowledge, the second reported case of lacrimal gland dirofilariasis in the literature and the second reported case of such a disease in Croatia.

Endonasal endoscopic orbital decompression in patients with Graves' ophthalmopathy.

AIM: To present the results of endonasal endoscopic orbital decompression in patients with Graves' ophthalmopathy. METHODS: Endonasal endoscopic orbital decompression was performed in 32 orbits of 21 patients with Graves' ophthalmopathy. In 17 patients the surgery was performed because of active ophthalmopathy non-responsive to conservative treatment, and in 4 patients for esthetic reasons. Preoperative and postoperative examination included visual acuity, examination of the eyelids and cornea, ocular motility, cover testing, Hertel exophthalmometry, and applanation tonometry. RESULTS: Visual acuity improved from preoperative 0.81+/-0.28 (mean +/- standard deviation) to postoperative 0.92+/-0.21 (p=0.0032, Student t-test). Retraction of upper and lower eyelids, as well as exposure keratitis, was reduced after operation (p<0.001). Mean proptosis reduction in all orbits was 4.6+/-1.7 mm (p<0.001). An average reduction of intraocular pressure was 3.4+/-3.0 mmHg (p<0.001). New-onset diplopia developed in 8 patients. Diplopia persisted in 9 out of 11 patients who had preoperative diplopia. Two patients experienced postoperative relief of diplopia. Ocular motility was subsequently corrected by eye muscle surgery in 13 eyes, whereas prisms were used in other 5 manifestly strabic eyes. CONCLUSIONS: Endonasal endoscopic orbital decompression procedure improved visual acuity, decreased proptosis and intraocular pressure, and also had favorable cosmetic results in most patients. Post decompression diplopia and strabismus were successfully managed by either eye muscle surgery or application of prisms.

A contribution to the surgery of the trachomatous entropion and trichiasis.

Although the WHO document WHO/PBL/93.29 recommends the bilamellar tarsal rotation operation for trachomatous entropion, we will describe another operation that has proved to be very reliable. It is a combined method, consisting of the modified tarsal wedge resection and the eversion splinting-grey line incision. A possible additional correction of the grey line incision on the first postoperative day improves the results. A total of 708 eyes with moderate trachomatous entropion and major trichiasis underwent this surgery, but only 508 of these were followed up during a 6-month period. The rate of failed operations, which consisted of incomplete closure of the lids or more than two inverted lashes remaining, was 6.9%.
